Her character Eleven also goes through a hair evolution. Millie told Renee her Season 1 hair was “quicker,” but her Season 2 hair was “much more fun.”

Bargh also caught up with Winona Ryder, who looked stunning in a black gown. Ryder revealed she got the dress at a bargain, “This is a $15 dress from Petaluma.”
